PROCESS F CASTING MACHINE PARTS.

Patented April 13, 1909.

Serial No. 456,058.J

Application tiled June 28, 1907,

Specification of Letters Patent. Serial No. 381,237. Renewed October 3, 1908.

the casting C is shown as square. By this means the member may receive a square rock shaft, whereby the two arms may be rocked as a unit to peritorm the work required. Several oi' these machine parts may be mounted ou one square shaft which, by reason oi' the square bore, may transmit power to them.

The two-arm structure shown is selected simply as illustrative ot the central idea oi' locking an arm to a sleeve. rlhese arms may be made ot sheet steel. The sleeve B is also preferably ot steel and may be very thin and light.

The material from which the casting is made is preferably some anti-friction material with a low melting point, as for example, a hard Babbitt metal. Fig. 4 illustrates the compound structure mounted in a suitable bearing D which may also be of Babbitt metal. It is to be noted in such mounting that the steel ot the sleeve B and the inner :taces ot the arms thus have their bearings on Babbitt metal, which reduces the triction. This is one ol the advantages of my invention, that it enables a steel bearing sleeve to be provided so that a cheaply cast bearing block may be used. The sleeve may be conveniently made ot hard drawn seamless tubing.

To all 'whom it fina/y concern:

Be it known that l, Josrrn T. Umnsiive, a citizei'i of the United States, residing at Cleveland, in the county ot Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Processes oi` Casting Machine Parts, ot' which the tollowing is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of the process constituting this invention is the production ot' machine parts comprising the combination ot a member selected for its strength or wearing qualities and a reinforcing member cast directly onto the member first mentioned and operating to stiften the same, change the efti'ective shape thereof, or lock together ditterent portions ot the member first mentioned.

The invention is herein illustrated as applied to the production of a machine part having a reinforced sleeve and two projecting arms, though it is to 'be understood that the process is not limited to producing this particular structure.

Figure 1 illustrates a mold by which my casting process may be carried into etteet; Fig. 2 is a perspective view ot a pair ot' metallic arms and a. metallic sleeve which are adapted to be looked together by n ly @Sting In making my compound arm, the first reinforce; Fig. 3 1s a partial section across Step 1S t0 mk@ the mms with Openings the parts shown in Fig. 2; Fig. it illustrates the complete structure with the reinforce applied, the structure being shown in place on a suitable bearing block; Fig. 5 is a longitudinal section through the complete structure; Fig. 6 is a fragmentary section on the line 6-6 of Fig. 5; Figs. 7 to 1st inclusive are views of various parts ot the mold shown in Fig. l; and Fig. is a vertical cross section of such mold.

Referring to Figs. 2 to 6, A A represent two flat arms which may be made of sheet metal; B represents a thin steel tube cont necting such arms and ilanged at l) over the i outer sides of the arms. These flanges prel vent the arms spreading but do not prevent l one moving with reference to the other. As shown in Figs. t, 5, and (i, C represents the reinforcing structure, which is cast through the sleeve B and over the ends thereof and along the sides of the arms, and continues 1 by lugs o into openings a in such arms. Such casting locks the two arms and the sleeve into one rigid structure. While the sleeve B is cylindrical, the bore c through through them and pass through such openings a sleeve B; then to pass the arms onto opposite sides of one of the two blocks L (see Fig. l) the sleeve occupying the semicircular depression Z in such block, the other block L being then placed against the outer side of the sleeve. lith the sleeve and arms in this position, the ends ot the sleeve are upset or lflanged by hammer blows on such ends. After the ends ot the sleeve B are upset, the plates M and N are placed above and below the two plates L, the arms A being turned to project across the short dimension ot' one ot the blocks L, such arms occupying the openings m and fn in the plates M and N respectively. Above and below the plates M and N respectively are plates P and Q, these plates being recessed at p and q so as to provide the proper shape I for the exterior ot' the casting C Above the plate P is a plate R having a series ot openings 1' near its center. Below the plate Q is a block S having a tubular boss s which is occupied by a liner s having a square bore. Occupying this bore is a square bar l l l l T which also occupies openings in the plates L, M, P, and Q, the end of the bar T abutting against the underside of the plate R between the holes 1". The various plates surmounting each other as described may be locked in place Vby pins U passing through them near the corners of the plates, four pins` being' provided; Bosses s2 are also shown on the underside of block S t0 receive these pins. Resting on the plate R outside of the holes 9 may be a tubular pouring sleeve V. WVith the parts in the position shown in Fig. l, the metal is poured into the sleeve V. lt passes through the openings r (Figs. 8 and l5) and flows into the space within the sleeve B and outside of the square rod T. The metal also passes onto the outside of the arms A and into openings a therein, its course being' defined by the recesses p and g. Suitable vents are rovided by grooves p and g leading from the openings p and g'. After the casting has been made, the sleeve V is knocked off in a direction parallel with the surface of the adjoining' plate P. This shears off the jets of metal which remain in the openings 7'. The square rod T is then removed, and the various plates removed, one after the other, leaving the completed compound structure above described.

The parts of the mold may be made of steel and may be used for an indefinite number of castings. After casting, it is only necessary to remove the parts of the mold and knock out the metal which remains in the holes r. On reassemblage of the parts the mold is again ready for use.

It Will be seen from the above description that my mold is a simple and cheap structure and is Well adapted for carrying out my process. This process, as pointed out, eects the triple result of enabling the employment of a thin bearing sleeve, of providing it with the desired angular bore, and of readily locking the parts of the structure together.

2. The process of making machine parts l consisting' of holding adjacent to each other a metallic sleeve and a member, and casting into thtx sleeve and onto the member beyond the end of the sleeve a reinforce, while employing means to produce a non-cylindrical bore within the sleeve.

8. The process of making machine parts consisting in taking a thin metallic sleeve and another member, holding them together by upsetting, and casting into the sleeve and onto the member material having a lower melting' point than such parts.

at. The process of making a machine part consisting' of taking a metallic sleeve, putting the sleeve through an opening 1n a metallic arm, upsetting' said sleeve on the outer side of the arm, and casting a reinforcing member extending through the sleeve and onto the outer side of the arm.

5. The process of making machine parts consisting of taking a cylindrical sleeve, passing' over the same a member having an opening substantiall f fitting said sleeve, and another opening' adjacent thereto, upsetting the end of the sleeve on the outer side of said member', and casting a reinforce extending through the sleeve and over the end thereof onto the outer side of the member and into the adjacent opening therein.

6. The process of making machine parts consisting of taking a cylindrical sleeve, passing over the same a pair of arms with openings closely fitting the sleeve and other openings adjacent thereto, upsetting' the ends of the sleeve on the outer sides of said arms, and casting' a reinforcing member extending through the sleeve and over the ends thereof and onto the outer sides of the arms and into the adjacent openings in said arms.

7. The process of making' a machine part consisting' of taking a metallic sleeve, putting the sleeve through an opening in a metallic arm, and casting a reinforcing' meniber extending through the sleeve and onto the outer side of the arm while holding an angular rod along the aXis of the sleeve to give the reinforce an angular bore.

In testimony whereof, I hereunto affix my signature in the presence of two witnesses.
